The coastal zone of Varandey, located in Pechora sector of Barents Sea, Northwest Russia, is exposed to active erosion processes, threatening any adjacent coastal infrastructures. Thermodenudation (thermal degradation of permafrost) and thermoabrasion (wave’s action on permafrost affected coasts) are erosive processes identified along the Varandey Coasts. Field investigations including trigonometric levelling have been combined with modern and archive satellite images analysis (from 1961 to 2012) of coastal erosion rates along the 80 km long coastlines in Varandey.

Keywords: coastal erosion, permafrost, thermodenudation, thermoabrasion

The atmosphere-ocean boundary layer in which sea ice resides includes many complex processes that require a more realistic treatment in GCMs, particularly as models move toward full earth system descriptions. The primary purpose of the workshop was to define and discuss such coupled processes...
